The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too ...

There might be a hidden ocean's worth of liquid water below the surface of Mars, seismic evidence suggests. According to a new paper published April 25 in the journal National Science Review, ...

Mars, now a dusty world of rusted rock and thin air, once carried enough water to transform its face into something far more ...

For years, scientists have been intrigued by mysterious dark streaks running down the slopes of Martian cliffs and craters. These marks, called slope streaks and recurring slope lineae (RSLs), have ...

How did Mars maintain surface liquid water billions of years ago? This is what a recent study published in AGU Advances hopes ...

A study by scientists at Penn State and NASA shows that intact biomolecules from dormant microbes break down much more slowly ...

A new study offers key insights into Mars' water cycle. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists have found seismic clues that ...

Seismic data collected by NASA suggests the amount of water hidden in the red planet's crust would cover its surface in a global ocean. Evidence is mounting that a secret lies beneath the dusty red ...

Mars has an active, electrically charged surface where dust storms and spinning dust devils regularly move and reshape the ...

For years, scientists have been looking for signs of liquid water just beneath the surface of Mars. The problem, though, is that the observations from various orbiting probes have been maddeningly ...

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars' polar regions were the only significant reservoirs of ice, ...
